[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0021] Example 1
[0022] This invention provides a shoe production system based on 3D printed models, such as... Figures 1 to 5As shown, the device includes a base 1, with a support frame 2 fixedly connected to the top of the base 1. A lifting platform 3 is movably connected to the outer surface of the support frame 2. The lifting platform 3 consists of a lifting table, a drive system, a control system, and a guide rail system. A 3D printing head 4 is movably connected to the outer surface of the lifting platform 3. The 3D printing head 4 consists of a nozzle, a heating block, a cooling system, a drive system, a stepper motor, and a control system. However, the 3D printing mechanism is not limited to the lifting platform 3 and the 3D printing head 4 described in this application. The lifting platform 3 and the 3D printing head 4 are the main structures of existing 3D printers. The specific working principle of the 3D printing head 4 (how it prints) is existing technology and will not be detailed here. A fixed plate 5 is fixedly connected to the top of the support frame 2. A rotating rod 6 is rotatably connected inside the fixed plate 5. A gear 7 is fixedly connected to one end of the rotating rod 6, and a positioning block 13 is fixedly connected to the other end of the rotating rod 6. A rack 8 is meshed with the outside of the gear 7. A slider 9 is fixedly connected to both ends of the rack 8. The slider 9 is slidably connected inside the fixed plate 5. A pressing block 10 is fixedly connected to the bottom end of the rack 8. A pressing rod 11 is fixedly connected to the top of the lifting machine 3. The pressing rod 11 is located directly below the pressing block 10. The two are not fixed. An anti-slip pad 12 is fixedly connected to the top of the pressing rod 11. When the lifting machine 3 drives the pressing rod 11 to rise, the anti-slip pad 12 can act as a buffer between the pressing rod 11 and the pressing block 10.
[0023] like Figure 1 and Figure 5 As shown, an arc-shaped block 14 is movably connected to one end of the rotating rod 6. A connecting plate 15 is fixedly connected to the top of the arc-shaped block 14. A spring telescopic rod 16 is fixedly connected to the top of the connecting plate 15. The top of the spring telescopic rod 16 abuts against a disc 17. The spring telescopic rod 16 presses against the disc 17.
[0024] like Figure 1 and Figure 5 As shown, a spring 18 is fixedly connected inside the positioning block 13, and a limit block 19 is fixedly connected to the top of the spring 18. The side of the limit block 19 away from the gear 7 has a beveled surface. When the disc 17 is fitted onto the surface of the rotating rod 6 and moves toward the gear 7, the disc 17 can press against the beveled surface, pressing the limit block 19 toward the inside of the positioning block 13. The disc 17 can pass smoothly through the positioning block 13. The limit block 19 is movably connected inside the positioning block 13, and the limit block 19 plays a limiting role for the disc 17.
[0025] like Figure 1 and Figure 3 As shown, the center of the extrusion block 10 and the center of the extrusion rod 11 are on the same vertical line, ensuring that the extrusion rod 11 applies force to the extrusion block 10 so that the extrusion block 10 can work normally.
[0026] like Figure 1 and Figure 3As shown, the diameter of the anti-slip pad 12 is larger than the diameter of the extrusion block 10. The anti-slip pad 12 is made of rubber to enhance the friction between the extrusion rod 11 and the extrusion block 10.
[0027] like Figure 1 and Figure 5 As shown, the center of the arc block 14 and the center of the rotating rod 6 are on the same horizontal line, ensuring that the arc block 14 can slide inside the rotating rod 6.
[0028] Working principle: In actual use, the device first aligns the disc 17, which is wrapped with rubber printing material, with the positioning block 13. Then, the disc 17 moves towards the gear 7. The inner surface of the disc 17 will contact the pressing block 10. As the disc 17 moves slowly, it will press the limiting block 19, causing the limiting block 19 to press the spring 18 and descend. After the disc 17 has completely passed the limiting block 19, the disc 17 no longer applies force to the limiting block 19. Under the elastic force of the spring 18, the limiting block 19 rises. The rise of the limiting block 19 will limit the disc 17, automatically limiting the disc 17 and preventing it from falling off during use, ensuring that the disc 17 can work normally. Then, the spring telescopic rod 16 will engage with the slot of the disc 17. When the disc 17 reaches the appropriate position, the elastic force of the spring telescopic rod 16 will press the arc-shaped block 14, which will also press and fix the disc 17.
[0029] Then, when it is time to print shoes, the lifting platform 3 will descend to the base 1. The descent of the lifting platform 3 will cause the 3D printing head 4 to descend synchronously. The descent of the 3D printing head 4 will pull the rubber printing material, causing the disc 17 to rotate. As the shoes are gradually printed and rise, the 3D printing head 4 will slowly move upward. After the 3D printing head 4 finishes printing, the lifting platform 3 will rise and cause the extrusion rod 11 to rise synchronously. As it continues to rise, the anti-slip pad 12 will push the extrusion block 10 to rise synchronously. The rise of the extrusion block 10 will cause the rack 8 to rise synchronously. The rise of the rack 8 will cause the gear 7 to reverse. The reverse rotation of the gear 7 will cause the rotating rod 6 to reverse synchronously. The reverse rotation of the rotating rod 6 will cause the disc 17 to reverse synchronously. The reverse rotation of the disc 17 can rewrap the unused printing material on the surface of the disc 17, which can automatically recycle the unused rubber printing material, reduce the material damage that may be caused by human operation, and also prevent excess rubber printing material from getting tangled inside the 3D printing head 4 and affecting its normal use.
[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
